My invention relates to improvements in wabblerholding mechanism and pertains` to that class where a wabbler is mounted toY wabble on a rotative power shaft and is held ..5 from turning thereon by the wabbler hold-v ing mechanism, which anchors the wabbler to the frame of the apparatus.

The Wabbler holding mechanism. heretofore has been mostly of the well known ring holding types.y

lVith that construction when running speedily the action of the wabbler is such that its action with its inertia of the mass of the wabbler, causes the Whole apparatus to tremble. It has an untruev and vibratory trembling motion every half revolutionof the power shaft, due to the holder ring holding the wabbler to wabblek ina straight spherical path straight with the power shaft,

(viewing it radially) t the holder ring and Y wabbler bearings. At otherpoints around the wabbler on its spherical working path such as the connecting rod and wabbler ball joints are caused to wabble, in .the form so I as to describe an imaginary figure like that of a figure 8 viewing it vradially'on any one of these joints. eachfiigure .increasing in width in proportion to the distance Vaway from said-straight spherical path, thus caus-` v3o ing the power shaft to be once speeded and retarded by acting on the inertia of the Wabbler every half revolution turned, causing an untrue torsion of the power shaft,'and a trembling of the entire device. l

The i invention yis shown... and .described herein as being used an internal combustion engine which. is onel of` best uses,.but it is applicableto pumps .and the like asv well.

I .40 The object of the'invention isito provide a simple and practical wabble holding mechanism that will hold the wabbler to the frame, to wabble uniformly' throughout its working cycle, whereby a tremblingr ofthe apparatus is eliminated, and a true torsion is delivered from the wabblerv to the power shaft, at all times and parts of the working cycle when running, also including balanc ing elements that balance the holder rods f .505 and partsthereffith so thatthe samejcan be counter-balanced bythe main crossforce.

counterbalance.

I attain these results with the. hereinafter described mechanism.

The equalizer and go and come member 9 is mounted freely'to the wabbler case or Y frame 10 in bearings lland 12one near each end ofthe equalizer and go and Vcorne member 9. "The wabbler case'or' frame 10 is fixed to the cylinder block 4; k.The equalizerand 'go and come. member-9 has 1a pair of Xed arms 13 and 14' at its ends extendingsto the right as seen in 'FigjL y r.Holdervrods 15 and 16 are connected at. their topfends with. ball joints 17 and 18 on` the lrespective holder'arms 18 and/14 and at their'lower ends by the respev y,

tive ball joints 19 and 20'Aon the respective outerends ofthe holder studs ,21 and 22. The inner` ends "of the holder studs 21 and 22 being Vfixed to ,the lower side of wabbler 6 at 23 `and 24, 90 apart and extending outwards from the center of the wabbler 6. an equal predetermined lengthy to .the yrespective ball joints 19 and20, 'which yoperategin a spherical Workingpath.

By the use of the combined equalizer and come and go member 9 and the holder rods and 16 connected up with the wabbler 6 and frame 10 in this manner, it is seen that the wabbler 6 can Wabble freely and is held to the frame 10 from rotating thereby.

In this instance there are eleven cylinders 27 in the cylinder block l in Which pistons 28 operate. To each piston 28 is lixe'd a piston stud 29 which supports the ball joint 30 that connects the piston 2S and one end of the connecting rod 31. The wabbler studs 32, 33 and 34 are liXed to the wabbler 6 and extend radially outwards therefrom a determined length to and supporting' the ball joints 25 that connects the other end of the connecting rod 31. Studs 33 and 34; in this instance eX- tend outwardly past the ball joint 2o and support respectively balancing Weight masses 35 and 36-90 degrees apart and each 90 degrecs from ,the respective holder studs 21 and 22 surrounding the Wabbler and around its axis, for balancing ball joints 19 and 20 and their associated parts so that those parts and balance weight masses 35 and 36 rcan be4 countenbalanced with c ounter-balar'ice weight mass 37 and 38 which are fixed to theV power shaft, Aone at each side of it and on each side of the Wabbl'er a predetermined distance therefrom so that the will cause a cross force on the power shaft, 1n the direction as indicated by the arrows, Which yopposes the cross force set up by the Wab-bler and parts that move with it in the direction asindicated bythe arrows, when running in either direction ofthe power shaft. Y

K By the use of the equalizing member 9, these holder rods 15 and 16, connected up withA the Wabbler 6 in this manner, it is -seen that the wabbler 6 can Wabble freely and uniformly and is held'to the wabbler case or frame 10 from rotating thereby, and holds the wabbler in such a manner proven by a 'Working model) that causes all 'of the ball j'oints 25 that Work in a spherical vpath in their movement to describe in said spherical path an imaginery figure like that of a ligure 8 shown at 26 Fig. 3, thus showing a uniform wa-bble throughout its working cycle, which causes it 'to work smoothly, land not produce a trembling motion when running speedily Aeach half cycle, as does the ordinary ty )e of ring Wabbler holders.

t may be noted that the length of the holder rods 15 and 16 respectively from one ball joint 19 and 20 to the other 17 and 18 are equal to they distance from one ball joint 17 to the other 18 on vthe holder studs 21 and 22, also the distance from one ho'lde'r arm ball joint 17 ofthe eqnalizing member 9, to the other 18 is the same as the distance fromfthe holder'stud ball joint 19 jto the Aother 20. 'tliis causes the uniform working of the wab'bler, and uniformly Adescribed imaginary figure Alike that of a ligure 8 of the 'several ball joints 25. i

lt is seen that all of the ball joints 17, 18, 19 and 2O necessarily Work approximately in the same spherical path surrounding the Wabbler, having a radius from either ball joint 19 or 20 to the center of the wabbler, and each approximately 90 degrees apart in said spherical path.

lt shall be noted that the term wabbler, means the wabbler proper and all parts fixed to it. y

It shall be understood that the phrases spherical path 7, means a Way in any direction that parts may pass, a certain radius from a sphericalcenter..

The necessary use of the equalizing and go and `come member 9 to allow a simultaneous go and come of the upper ends of the holder rods at ball joints 1"? and 18 every time the wabbler makes a half working cycle, and the pull on one holder rod and push on the other, by ythe wabblcr, is equal to each other at all times when the power shaft is working in either direction.

The device is not "hewn supported, but may be supported in any suitable manner.

lt shall be miderstood that the term equalizing member includes all parts fixed to the eqnalizing and go and come member 9.
